Some epic spells are very nice, such as the mass vampiric leech thing and the epic gate. Such spellls and abilities are best used in the toughest fights in the game, and they can make a difference.

By the way, the 29 Wisdom required for dragon shape is buffed or unbuffed? If it's unbuffed, which I suspect it is, that feat is virtually impossible to get - you get 7 points extra from level 1 to 30, so you'd have to start out with 22 Wisdom. If it's buffed (through items, for example), it would be almost too easy to get, since there are items giving +6 (and more) Wisdom.
